QUOTE(dunhill1410 @ Apr 2 2010, 08:48 PM) want bit idea about the free Nokia Ovi maps for couple of phones..any help? if you're new to phone gps, nokia ovi maps is the perfet place to start with. it has very fast initial gps satellite lock down period, and the map can be panned around and zoomed in/out without any lag. unluckily, the roads and POIs are awfully skimpy.

I upgraded from the Nokia Maps 3.01 to 3.03 and the newer version has much better integration to the phone. Furthermore, the 3.01 needs a minute or more to lock onto satellite without using AGPS. But the 3.03 can lock on within seconds. But a word of caution. The new 3.03 seems to use 12MB more of the phone memory. Yes, a whopping 12MB more.

Hello,
i'm very interested to get a GPS phone. Been carrying my leica GS20 around, which is bulky. I'm wondering will any smart phone has the capacity to support GIS software like ArcPAD? Also, will existing GPS phone be able to give GPS reading for 'off road' condition. Means if i am standing in middle of a football field middle of a felda settlement instead of on Jalan Bukit Bintang, will the phone still able to get my location? As i understand, currently most phone GPS are A-GPS, so if off road, will it still be able to function well?
Another question, if smart phone can support GPS as of GS20, will the phone be able to receive JUPEM's MyRTKnet DGPS correction?
I'm looking at Nokia E72. Any comments? thanks.

Can only answer part of your question. Without AGPS, the Nokia can still locate the satellite and give you your co-ordinate anywhere in the world. All you need are clear sky and patience...say....a couple of minutes.

I can say that the GPS performance is excellent !! never taking more than 5 minutes to lock[I disabled the A-GPS] usually in less than 2 minutes... and sometimes not even a half minute[as I'm always use]

Once you got satellite lock while standing at Location A, then switched off GPS and switched on again, it can re-acquire satellite lock within seconds. But once you move to another Location B that is a few kilometer away, ti will take a couple of minutes. Once I went to Location C that is a thousand kilometer away, it took about 5 minutes or more on my E52. Of course not using AGPS. This post has been edited by Optiplex330: Apr 5 2010, 07:05 AM

The GPS co-ordinate are supposed to be within 10 meter accuracy. But from the reading I got with Nokia Maps and Garmin on my Nokia phone and then comparing it with google satellite map, sometime they can be as far off by 40 meters. At other times, they can be dead accurate. Anyone noticing that? So, how to improve accuracy all the time?

For better accuracy get the external antenna or re-radiating antenna if you don't have the socket. http://www.gpsinformation.org/dale/gpsant.htm

So, how to improve accuracy all the time? turn on A-GPS & network based option and u might improve ur accuracy. open ur window for both drivers and passengers side (the tint on ur window affects the accuracy) 40 metres is still acceptable la anyway, quite common

Yet the reading can sometimes be inaccurate. Checking on Google map of places I am familiar, the reading can be off by 20 - 40 meters instead of the supposedly 10 meters. So either the google map is inaccurate or the GPS reading is. Any idea? This post has been edited by Optiplex330: Apr 6 2010, 12:24 PM

Ehhh Long time din use google map dy..Isn't google maps using data charges to refresh the GE data?
Anyway, trust me use a re-radiating antenna sure accurate wan..It's pretty normal sometime the accuracy will run. Nothing new because of the low signal strength.
Wth re-radiating antenna, it will boost the signal abit. I bought similar set from the Hong Kong site above.

Any idea? maybe ur built-in gps' prob.. no offence.. cause i once bought a n95 8gb and the garmin shows 1 bar only while my bro's shows 4 bars. totally same settings

AGPS only makes it easier to pick up the satellite signal and after that, other factors (not AGPS) affecting accuracy comes into play. Signal reflected from surrounding building etc and others I don't know about. This post has been edited by Optiplex330: Apr 8 2010, 12:29 PM
